A critical bug in Microsoft Access version 2412 has rendered the mousewheel event non-functional, impacting form and report navigation.

## Bug Description

The bug specifically affects the Form's [MouseWheel event](https://learn.microsoft.com/en-us/office/vba/api/Access.Form.MouseWheel%28even%29)'s two key arguments - **`Page`** and **`Count`** \- which are meant to trigger when users scroll through forms or reports.

In version 2412 build 18324.20092 and subsequent builds, these arguments consistently return **`False` for Page** and **`0` for Count**, effectively breaking the mousewheel scrolling functionality that many Access applications rely on.

## Current Workaround

The only known workaround as of today (2025-01-17) is to [roll back to version 2411](https://www.accessforever.org/post/roll-back-to-previous-versions-of-office).

[Roll-back to previous versions of OfficeIf an update for Microsoft 365 contains a relevant bug, we will inform you on AFo about workarounds and the planned fix date. But sometimes it is unavoidable to quickly roll-back such updates until the problem has been fixed by Microsoft.This article will show three different methods to roll back undesired updates. See methods 1 and 2 for all click-to-run (CTR) versions of Microsoft 365 and Office. For MSI versions, use method 3 below.PreparationsFollowing steps are necessary before rolling back![](https://static.wixstatic.com/media/3d02f3_9178f2d10cff42fcbb85020ff2061442~mv2.png/v1/fill/w_192%2Ch_192%2Clg_1%2Cusm_0.66_1.00_0.01/3d02f3_9178f2d10cff42fcbb85020ff2061442~mv2.png)AccessForeverPeter Doering![](https://static.wixstatic.com/media/e24849_cf560de0359d4780a10f32ee3640dc9f~mv2.png/v1/fill/w_720,h_480,al_c,lg_1,q_85/e24849_cf560de0359d4780a10f32ee3640dc9f~mv2.png)](https://www.accessforever.org/post/roll-back-to-previous-versions-of-office)
